Liston: 28 days Short summary, main achievements and difficulties encountered during field season (150 - 250 words) Regional snow cover in North East Greenland In April 2014, good snow conditions and clear weather enabled us to traveling on snow mobiles across a region stretching 100 km from the most eastern point of Wollaston Foreland, through the broad valleys around Zackenberg Research Station, and into the inland parts of Tyrolerfjord and Store Sødal with their mountainous terrain. We collected snow observations in 44 snow observational sites. In each site, we conducted snow depth transects (in total 8400 snow depth measurements), dug snow pits to measure snow density and observe stratigraphy, and noting snow crystal sizes and hardness. The observations of the landscape and snow distribution across the region in April 2014, gave an impression of a decreasing wind speed gradient from the coast and inland direction. We, therefore, expect to identify a gradient of decreasing winter precipitation amounts as well as decreasing wind speed across this region from east to west in the extensive snow dataset collected through April, which is currently being analyzed.

Abstract: Arctic environments experience rapid climatic changes as air temperatures are rising and precipitation is increasing. Rivers are key elements in these regions since they drain vast land areas and thereby reﬂect various climatic signals. Zackenberg River in northeast Greenland provides a unique opportunity to study climatic inﬂuences on discharge, as the river is not connected to the Greenland ice sheet. The study aims to explain discharge patterns between 1996 and 2019 and analyse the discharge for correlations to variations in air temperature and both solid and liquid precipitation. The results reveal no trend in the annual discharge. A lengthening of the discharge period is characterised by a later freeze-up and extreme discharge peaks are observed almost yearly between 2005 and 2017. A positive correlation exists between the length of the discharge period and the Thawing Degree Days (r = 0.52, p < 0.01), and between the total annual discharge and Citation: Ploeg, K.; Seemann, F.; the annual maximum snow depth (r = 0.48, p = 0.02).

F. SPATH D.Sr.., F. R.S. K0 BENHAVN C. A. REITZELS FORLAG BIANCO LUNOS BOGTRYKKKKI 1946 retaceous ammonites have long been known from East Greenland C but the list of the few, more or less isolated finds is not impressive. Thus Toula’s (1874) widely-quoted Amm. payeri, first referred to the genus Perisphinctes, was subsequently considered to be a form of Sim- birskites and was held to demonstrate the presence of marine Hauterivian deposits. This is almost certainly incorrect, as mentioned below. Again one of Ravn’s (1912) two ammonites was misidentified as a Neocomian “Garnieria”, whereas in reality it represents the inner whorls of an Aptian genus (Sanmartinoceras). A few additional species were recorded by Koch (1929, 1931), Rosenkrantz (1930, 1934), Frebold (1935) and Maync (1940), again mostly of Aptian age. The purpose of the present note is not only to amplify these records but to announce the discovery of entirely new ammonite assemblages of Cretaceous age. The new collections were made during the 1936—1938 expedition to East Greenland under the leadership of Dr. Lauge Koch, and the collectors of the material now before me were two competent Swiss geologists. One of them, Dr. Hans Stauber, worked in Traill Island and Geographical Society Island. The other, Dr. Wolf Maync, collected in the northern area, from Clavering Island up to Kuhn Island.

MICROBIAL COMMUNITY COMPOSITION, EXTRACELLULAR ENZYMATIC ACTIVITIES, AND STRUCTURE-FUNCTION RELATIONSHIPS IN THE CENTRAL ARCTIC OCEAN, A HIGH-LATITUDE FJORD, AND THE NORTH ATLANTIC OCEAN John Paul Piso Balmonte A dissertation submitted to the faculty at The University of North Carolina at Chapel Hill in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Department of Marine Sciences in the College of Arts and Sciences. Chapel Hill 2018 Approved by: Carol Arnosti Andreas Teske Ronnie Glud Barbara MacGregor John Bane © 2018 John Paul Piso Balmonte ALL RIGHTS RESERVED ii ABSTRACT John Paul Piso Balmonte: Microbial community composition, extracellular enzymatic activities, and structure-function relationships in the central Arctic Ocean, a high-latitude fjord, and the North Atlantic Ocean (Under the direction of Carol Arnosti and Andreas Teske) Due to their abundance, diversity, and capabilities to transform and metabolize diverse compounds, microbial communities regulate biogeochemical cycles on micro-, regional, and global scales. The activities of microbial communities affect the flow of matter, energy sources of other organisms, and human health, as well as other aspects of life. Yet, the composition, diversity, and ecological roles of microbes in parts of the global oceans— from the high latitudes to the deep water column—remain underexplored. Drawing from microbiological, oceanographic, and ecological concepts, this dissertation explores several fundamental topics: 1) the manner in which hydrographic conditions influence microbial community composition; 2) the ability of these microbial communities across environmental and depth gradients to hydrolyze organic compounds; and 3) microbial structure-function relationships in different habitats and under altered environmental conditions.

Progress in Oceanography Progress in Oceanography 71 (2006) 426–445 www.elsevier.com/locate/pocean Carbon cycling in a high-arctic marine ecosystem – Young Sound, NE Greenland Søren Rysgaard a,*, Torkel Gissel Nielsen b a Greenland Institute of Natural Resources, P.O. Box 570, 3900 Nuuk, Greenland b National Environmental Research Institute, Department of Marine Ecology, Frederiksborgvej 399, DK-4000 Roskilde Abstract Young Sound is a deep-sill fjord in NE Greenland (74°N). Sea ice usually begins to form in late September and gains a thickness of 1.5 m topped with 0–40 cm of snow before breaking up in mid-July the following year. Primary production starts in spring when sea ice algae begin to ﬂourish at the ice–water interface. Most biomass accumulation occurs in the lower parts of the sea ice, but sea ice algae are observed throughout the sea ice matrix. However, sea ice algal primary production in the fjord is low and often contributes only a few percent of the annual phytoplankton production. Following the break-up of ice, the immediate increase in light penetration to the water column causes a steep increase in pelagic pri- mary production. Usually, the bloom lasts until August–September when nutrients begin to limit production in surface waters and sea ice starts to form. The grazer community, dominated by copepods, soon takes advantage of the increased phytoplankton production, and on an annual basis their carbon demand (7–11 g C mÀ2) is similar to phytoplankton pro- duction (6–10 g C mÀ2). Furthermore, the carbon demand of pelagic bacteria amounts to 7–12 g C mÀ2 yrÀ1.
